Abstract: An artificial tooth manufacturing information generation method is provided. The artificial tooth manufacturing information generation method may include the steps of: photographing a target tooth to acquire a primary image; correcting the primary image to acquire a secondary image; selecting an area including the target tooth from the secondary image to extract a tertiary image; selecting a noise area caused by reflected light from the tertiary image and then correcting the noise area, to acquire a quaternary image; and generating artificial tooth manufacturing information by using a pixel value of the target tooth included in the quaternary image.

Abstract: Provided is a method of forming a customized alveolar bone tissue. The method includes obtaining first data having image information corresponding to an original alveolar bone of an alveolar bone defect, obtaining second data having image information on a defective portion of the alveolar bone defect, calculating third data having image information on a barrier membrane covering the alveolar bone defect by using the first data and the second data, and forming a barrier membrane artificial tissue corresponding to the barrier membrane by using the third data.

Abstract: The present invention relates to a saliva collection device. A saliva collection device according to one embodiment of the present invention comprises: a saliva collector part which is provided in a vessel shape open at one side thereof and has an inner collection space open at one side thereof; a saliva movement part having a predetermined length, connected at one end thereof to the saliva collector part, and provided in a pipe structure having a saliva movement passage connected to the collection space; and a saliva collection part connected to the other end of the saliva movement part and having an inner space in which saliva can be stored.
